` vEHrcLE-HUB.

-yhub supplied .with a pneumatic tire, and

with means-y vof protecting the tire fromA puncture and Wear. This object is attained by the means described inthe specification' and illustrated inthe accompanying drawings, in which, a l I Figure lis a view partly in elevation, and partly in section uponlinl:y 2-2 of Fig. 2 of a vehicle hub embodying my invention. Fig. 2 is a central of Fig. l. Fig. 3is a detail view of the ends ofthe pneumaticv'tire and themeansof. connecting them. p y

Referring to the parts :the wheel consists of a primary wheel which has rim, A, with a cushion tire, a,spokes, a', and a hub,'a2, and al secondary wheeljwhich has a pneumatic tire, B, a rim, b, spokes, b and a hub' whose sleeve, b2, is journaled-upon'the axle, C, of the vehicle. The hub ofthe-secondary wheel consists yof a circular disk, b3, -formed in:

tegral with4 thezslee've, 722, and of a circular', disk, 64, which is secured to the sleeve, b2, by

screws, b5. The spokes, b', ofthe secondary wheel are screwed intosockets in .the peripheries of .the disks,- 63 b. Upon the inner [faces ofthe disks, b4, are radial* grooves, be, 'b2-bs and b". The lll/1b, 5.2, 0f

' Z114, screw-threaded at its ends to fit sectional view -upon line 'Pina da? i Spokesd, are laterally expanded solas to form oval yokes, as, which pass over 4the Patented .Tune 8, 1909. ,i

pneumatic tire, B, and the rim, b.- Between the periphery of the tire, B, and the yokes as, are two semicircular sheaths, E, E', which are secured to spokes by screws e. Pneumatic tire, B, 'is a flexible tube closed at both ends, one end, b1", bein forked and*w the other end, b, being pointe to dove-tail into forked end, b1, each end carrying a nipple, Z212, 1113, to be connected by la tube, onto the nipples, bu, Z213. Sheaths, EE, are perforated at` e2, es, to pass the nipples, b1?, b1".

' In use it'is seen that the pneumatic tire never domes in contact with the ground, which is contacted only by a:'The vibration of the vehicle is cushioned by the pneumatic tire, B, because of the play between the secondary andprimary wheels, which takes place -at their hubs, because of the movement of the pins, d, d, d2 and als, in the grooves, a4L through a7, and b6 through b9.

4 In a vehicle the combination of a secondary i and a primary wheel, the secondary wheel consisting of a hubmade up of two disks connected byv a sleeve. to be Journaled upon an axle, a rim, spokes joining the disks o the hub to the rim and a pneumatic tire seated on the rim, and the primary wheel consisting of a hub surrounding the sleeve between the disks, and having a bore of greater diameter than the diameter of the sleeve, a rim of larger `diameter thantha't of the secondary wheel and spokes'connecting the hub of the primary wheel with its rim and having yokes surrounding the rim of the lsecondary "wheel, and contacting the outer periphery4 of the neumati'c tire, the adja- 'cent faces of the' isks andthe hub of the primary wheell having Vradial and sectoral l,grooves `andpins seated in the grooves .to

ay between the said-hubs.'
